The purpose of this document is to identify potentially hazardous substances that may be in use in many school laboratories and to provide an inventory of these substances so that science teachers may take the initiative in providing for the proper storage, handling, use, and if warranted, removal of hazardous materials. The document consists of…

A workshop was designed to (1) train teachers to become experts on chemical safety and storage; (2) examine and evaluate chemical storage in 12 Carroll County (Maryland) schools; and (3) develop a safety guide for all county science classrooms. Development, implementation, evaluation, and implications of the workshop are addressed. (JN)

Describes a demonstration involving the controlled combustion of a mixture of metals with black and smokeless powder in a small Erlenmeyer flask. Also describes demonstrations using a device that precludes breathing of hazardous vapors during class demonstrations; the device is easy to transport and use in rooms without sinks. (JN)

Discusses six common problems which may occur when using temporary labels on chemicals, samples, or mixtures in teaching or research laboratories. Solutions to each of these problems are offered. (JN)

This handbook was prepared to help science teachers, administrators, and other school staff members understand and avoid situations in which accidents might occur in the science laboratory, on field trips, or during outdoor education experiences. Suggestions contained in this publication are generally agreed upon and recommended for consideration…

Describes a prelab activity, the chemistry report, that acquaints college students with the nature of the chemical(s) they are using in the laboratory. Methodology, experimental procedures and safety rules are emphasized, with particular emphasis on potential hazards, safety requirements and emergency procedures. (CS)

Discusses the possible dangers of the educational radioactive sources used in a college physics laboratory. The discussion is intended to increase the awareness of teachers and students. (HM)

Discussed are accidents that occur in the laboratories of highly trained chemists. Four examples are provided to illustrate potential hazards that are often overlooked in chemistry laboratories, molten inorganic salt baths, the reaction of acetone and hydrogen peroxide, halogenated acetylene compounds, and the reaction of hydrogen peroxide and…

Describes a method for the preparation of hydrogen gas which is safer than conventional procedures. The procedure and equipment are described in detail. (BR)

This module provides safety guidelines for vocational teachers, principals, and students in the vocational shop class, including tips on the prevention and handling of accidents if they occur. It answers questions on student and administrator liability in accident situations. Suggestions are included for increasing the safety of special needs…

Provides information on updating older fume hoods. Areas addressed include: (1) adjustment of the hood's back baffle; (2) hood air leakage; (3) light level; (4) hood location in relation to room traffic and room air; and (5) establishing and maintaining hood performance. (JN)

Describes procedures for disposing of dichromate cleaning solution, picric acid, organic azides, oxalic acid, chemical spills, and hydroperoxides in ethers and alkenes. These methods have been tested under laboratory conditions and are specific for individual chemicals rather than for groups of chemicals. (JN)

Highlights guidelines that should be implemented in administering a plan for the proper storage of chemicals. They include housing chemicals in multiple locations within a building to lessen the accident potential, not grouping them in alphabetical order, and storing them according to six major chemical classes. (JN)

The purpose of this safety manual is to provide a resource to help manage and minimize potential risks in science classrooms where students spend up to 60% of instructional time engaged in hands-on activities. Information on general laboratory safety, science equipment safety, safety with plants, safety with animals, safety with chemicals, field…

Reviews the dangers of benzene as a toxin as well as a flammable substance. (CS)
